In the case of a door or casement window which opens outwards, the fastening device would be secured to the edge of the door or window instead of to the stationary surround and the bolt, when operated, would make contact with the surround.

Fig. 9 shows the application of the invention to a sliding sash window. The fastener is secured to the bottom rail l8 of the upper sash and the bolt I, when in the fastening position, will make contact with the upper rail 19 of the bottom sash. With the parts in the position shown the bottom sash cannot be raised nor can the upper one be lowered. The sashes slide in the direction of the arrows 20 and the bolt 1 is moved in the same' direction when moved into and out of the fastening position.

If desired the lever 9 can be operated other than by direct manual pressure. For example it may be moved by a third lever, cam or the like which in turn is manually or otherwise operated. Again the operatinglever may be operated mechanically by a cable, or it may be connected to the armature of a solenoid or electro-magnet and be moved upon the closure of the circuit of the electromagnetic device. Such arrangements allow of remote control. Provision may be made for the bolt operating mechanism to be tripped automatically upon the closure .of the door or the like, the final part of the closing movement of the door being used to accomplish this; an arrangement of this kind is useful when the fastener is used for a gate.

Other modifications may be made without departing from the invention. For instance, instead of piercing the lug 3 for receiving a screw or the like, the lug may be provided with a permanently attached pin, spike or the like which is pushed into a door jamb or the like and, not being subjected to end pull if pressure is applied to the door, this pin provides a sufliciently firm fixing for the fastener to enable it, if desired, to be applied temporarily toa door or the like, such as when travelling. Again, instead of a toggle arrangement any other mechanism can be used which will turn the bolt and lock it in the fastening position and preferably lock it also in the retracted position.

,I claim:

1. A fastening device for doors, windows and the like, comprising a housing having a mounting base, a bolt pivoted in said housing to swing into and out of one end .of the housing in a plane substantially perpendicular to said base, the bolt being adapted to project in its fastening position beyond the said end of the housing and in substantial alignment with the base, a separate pivoted operating lever having a pin and slot connection with the bolt for operating the same, the pin of said pin and slot connection cooperating with the appropriate end of the slot thereof in either of the bolts fastening and disengaged positions to lock the bolt therein against displacement under force applied to the bolt.

2. A fastening device for doors, windows and the like, comprising a support having spaced apart sides, an operating lever having spaced apart sides disposed longitudinally of and between the sides of the support and pivoted thereto near the top of the support, a pin at one end of said lever carried by and extending across the sides thereof, an angle lever bolt disposed longitudinally of and pivoted between the sides of the support near the bottom and near one end thereof the bolt having a slot in one lever arm thereof and the pin carried by the operating lever passing through said slot, the free end of said operating lever being adapted to be manually operated, the bolt upon operation of said lever being adapted to be turned on its pivot by the coaction of said pin and slot between its fastening position where said other lever arm of the bolt projects beyond the end of the support and its disengaged position where the bolt is retracted to bring its said other arm within the support, the end of the operating lever that carries said pin and said bolt being adapted to nest one within the other upon the bolt being retracted, said pin cooperating in each of said positions with an end of said slot to lock the bolt against movement other than that applied through said lever.

3. A fastening device as defined in claim 2, wherein the bolt is of substantially triangular shape having the said slot located along a side adjacent the bolts pivot, the other side adjacent the bolts pivot constituting the working face of the bolt.

4. A fastening device for doors, windows and the like, comprising a channel-shaped support, an inverted channel-shaped lever disposed longitudinally of and between the channel sides of the support and pivoted intermediate its ends thereto near the top of the support, a pin at one end of said lever carried by and extending across the channel sides thereof, a channel-shaped bolt disposed longitudinally of and pivoted at one end between the channel sides of the support near the bottom thereof and near one end of the support, the bolt being turnable between its fastening position where it projects beyond the said end of the support and its disengaged position where the bolt is retracted within the support, the bolt having a pair of aligned slots in its channel sides at their inner ends, said pin carried by said lever extending into said slots, and the end of said lever that carries said pin and the channel sides of the bolt being adapted to nest one within the other upon the bolt being ret-racted, the free end of said lever being adapted to be manually operated, the bolt upon operation of said lever being adapted to be turned about its pivoted end by the coaction of said pin and slots, said pin cooperating in each of the bolts positions with an end of said slots to lock the bolt against movement other than that applied through said lever.

5. A fastening device as defined in claim 4 and comprising a. compression spring disposed between the bottom of the support and the lever adjacent its pivot, said spring being compressed to a dead centre position upon operation of the lever in either direction whereby to impart a snap action to the device.
